Kathryn grew up playing football, but tore a ligament in her knee prior to starting University. Therefore, instead of playing football, Kathryn learned to row during her first year at University and continued to row for the duration of her degree. Kathryn graduated from Dartmouth College in 2009 with a double major in Physics and Chemistry and a minor in Biology. Kathryn is currently working towards a PhD in Physical and Theoretical Chemistry at the University of Oxford on a Rhodes Scholarship.

In her spare time, Kathryn enjoys hiking and biking, particularly in the mountains, or along the coast.
